In the machine age of today more
& more focus is given on production & capacity of the
plant. Thus longer life, higher durability & that to at
economical rates are some of important characteristics required
for machine parts.
Even the smallest user is constantly demanding for increase
in life & maintenance free parts for his machine. Simultaneously
this revolution as demanded improvement in materials used
for cutting, mining & wear part applications. Also of
existing material like carbon steel & HSS were are not
reliable for higher speeds & feeds.
Here is where, Tungsten carbide (also called
Cemented Carbide ) come into picture.Though toughness of this
material was well known, it achieved its technical break through
in 1920s, when it was discovered that combination of
Tungsten Carbide & Cobalt, when compacted under pressure
& sintered at higher temperature, produced a material
that it is highly favorable for mechanical application as
it covers wide range of combination of hardness & toughness.
With further additions like Titanium & Titanium, Carbide
has gained increase in many industrial application like, metal
forming, mining tools, wear parts & corrosion resistance.
Tungsten carbide is a high-tech product.
Though a bit expensive than best Steel available Carbide
have the abilities that justifies the extra cost by reducing
the cost per unit of finished product & effect in working
hours. An experienced machinist would choose a hard metal
strength just enough to bear the loads & has optimum resistance
to wear & tear. Such selections can be perfected using
various grades from same manufacturer depending upon same
manufacturer depending upon the various priorities desired.
